Definition of CAT III
This instrument, in overvoltage category III, meets with the
strictreliabilityandenvironmentalrequisitesthat apply to fixed
industrial and domestic installations
(see IEC 664-1 ed 92).
Thank you for purchasing a C.A 861 or C.A 863 hand-held
thermometer.
To get the best service from this instrument:
nread this user’s manual carefully,
nrespect the safety precautions detailed
!
SAFETY PRECAUTIONS
!
■To prevent any risk of deterioration to the thermometer, do not
use with sensors raised to voltages exceeding 24 V AC/DC,
since the sensors are electrically connected to the
thermometer input.
■If the thermometer is subjected to great variations in ambient
temperature,waitfor20 minutesafteritbecomes stableagain
before continuing with measurement.
■Respect the climatic environmental conditions (see §4)
WARRANTY
Our guarantee is applicable for twelve months after the date
on which the equipment is made available (extract from our
General Conditions of Sale, available on request).

1.PRESENTATION
The C.A 861 and C.A 863 are high precision hand-held
temperature measurement instruments, lightweight, with
digital display, and easy-to-use with interchangeable K-type
thermocouples.
2. DESCRIPTION
See §7. Appendix (found at the end of this user’s manual)
➀Converters for K-type thermocouple sensors
➁LCD display, back-lit
- Main display: digital temperature value (±)
3½ digits or OL error
- Symbols :
KK-type thermocouple sensor
Low battery
Last measured value
°C/°F Unit of displayed value
MAX Maximum temperature value
T1-T2 Difference ∆T betweenT1 andT2 (C.A 863) (see §3.2)
➂2 function button:
Long press > 2 secs: choice of unit used
Short press: switches display backlighting off and on
➃Push button:
Short press: stores last measurement display
Held press > 2 s : Max. measured value (C.A 863)
➄3 position selector switch:
- Thermometer off
- 1°C or °F Resolution
- 0.1°C or °F Resolution

➅C.A 861 :
Command push button for max. temperature value
C.A 863 : Scroll-down menu for going from T1 to T2 and
then ∆T.
➆Shock-proof moulded surround
3. USE
3.1 Procedure
1. Connect one or two sensors
2. Switch on the thermometer:select one or two measurement
resolutions, using selector switch ➄, the measurement is
instantaneously displayed.
3. Set-up the thermometer according to the type of
measurement to be carried out, using buttons ➂,➃ and/or
➅ (see §2 and 3.2) .
4. Read off the measured value.
The thermometer is switched off by putting switch ➄back in
the OFF position.
Note :
If no sensor is connected, OL Is displayed.
If the temperature to be measured is outside of the instrument’s
measurement range, then OL is displayed.
3.2 Special Functions (see §2. Description)
HOLD :as soon as this button is pressed, the instrument holds
the last measurement displayed.
MAX: the instrument displays the maximum value of the
temperature during measurement

∆T: With two sensors the instrument simultaneously
measures temperatures T1 and T2 and displays the
difference ∆T between these two measurements.
